The computer displays the progress at the bottom indicator, then, before that can display the login screen, the screen goes black, with a white cursor. CTRL-Alt-Del and Ctrl-Shift-Esc do nothing.

    I tried without success to the following:

    * Startup Repair - told me there is nothing wrong
    * System Restore - tells me there is no available restore points
    * System restore the OEM DVD - can not find hard drive
    * Re-install this is disabled because I can't start Windows Vista-

    There are * all * options other than wiping the disc/lose all my data? The PC is in a remote area and backup drive is not an easy thing to achieve.

    The PC is no longer under warranty of the bridge, and I understand that Microsoft supports is no longer installs OEM of Vista.

    Download the ISO on the provided link and do a repair of the disc.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

  • Get a black screen BIOS afer and before Windows logon

    So get a black screen after BIOS and before the Windows logon screen. I checked the RAM and one on two RAM sticks that was bad. But I still have the black screen. I tried an external monitor but still a black screen. I tried all the normal things (verification of the restore point disc, e.g. via the command prompt, startup repair, etc.) and no luck. I ran a test to check the hard drive, and it is impossible to find the hard drive. But then I ran AVG anti-virus, the AVG Live (bootable CD) and at the very start gave me this error: 106 error to the power of disk on life: 8768 (365 days + 8 hours) and underneath were basically the same error, just different numbers. But it still allowed me to run a scan and he was going through the files ok so she did not see the hard drive and files (contrary to the test of hard drive and yes the hard drive test was a bootable cd of same manf. like the hard drive), he found no virus. Even when I ran Defender in offline mode. Then I tried to re - install the operating system on the same drive with a cd. When he was going through the first part of the establishment where it was drivers and so forth: I kept getting the BSOD. Then I took the drive from the laptop and install it in another laptop but she has done the same thing, black screen, so I thought it was the hard drive. But then I begin another hard drive from the laptop and put it in the laptop original and he gave me the black screen and I know that the hard drive was good, she was an operating system that starts when I put it in the not troubled laptop. So any ideas anyone? Would it be possible that the all three things at once: RAM and hard drive laptop motherboard? Any help would be appreciated.

    Hello

    Error code 24 characters for short drive Self Test (DST) would indicate that hard is defective and must be replaced.  It is also compatible with startup problems you describe.

    If your laptop is still under warranty, contact HP and arrange for the disk replaced - you can check the status of your warranty here.

    If you live in the United States, contact HP here.

    If you are in another part of the world, begin here.

    If you are out of warranty and would like a guide to replacing the hard drive yourself, let me know.

  • Inspiron M5030 black screen at startup

    As the topic says, when I boot my dell Inspiron M5030, I just get a black screen, no beep and yes I have connected externally on a monitor without success. It was working fine a few days ago, I stopped and went to bed, got up the next day and it started. The power led lights up, the HARD drive light turns on and blinks so I know that something is written or read from the HARD disk, but I don't get the POST screen that says DELL or anything... Just a white screen. I would say that is the back light but the screen has a white tint to it and to my knowledge it is the backlight on the screen.

    I checked the RAM, HARD drive, etc. Check that it has been placed correctly yet.
    I removed the MOBO battery hoping to reset the CMOS to maybe get a kind of screen, but this resulted in the 'time Off system' (5 beeps) beeps but they stopped after a reboot.

    What I ended up doing was remove the heatsink from the CPU and video chip and they had as a rubber stamp on that foam.  I removed that and put thermal paste and it works fine.  Sometimes if I use it everyday the screen may start off dead zone but up to now no more beeps at startup.  If you do what I suggested before it won't hurt her, but I recommend to do what I explained in this post, after get you to the top and running.  I would like to know how it works.
